Abstract: 728,927. Making reticulated sheets. GLOBE CO. Oct. 10, 1952 [Oct. 12, 1951; March 8, 1952], No. 25405/52. Classes 83 (2) and 83 (4). Shearing.-In making reticulated sheets for gratings &c. aluminium or steel sheets are formed centrally with corrugated' slits transversely of the sheet, Fig. 10, and the slits are opened out by blank punches to set the corrugaged edges normal to the plane of the sheet, Fig. 2. The sheets are fed intermittently by roller or other means between cutters 150, 160, 170, 180 cooperating with cutters 190, 200, 210, 220 on reciprocated bolsters 120, 110. On the first descent of a head 110 four corrugated slits A, B, Fig. 10, are made by the cutters 170, 180. The sheet is then fed a distance equal to twice the spacing of the cutters 170, 180 and alternate three corrugation slits C, D are made on the next descent. The sheet then passes under straightening dies 250, 260. The sheet is guided by lower spring-supported plates, one with a guide edge, and is clamped at the edges by co-operating spring-pressed plates, Fig. 6 (not shown), which carry a punch for forming a registration hole 500 in the edge of the sheet and registering pins which locate the sheet after each feed movement. Upper and lower bolster plates 130, 140 carry oval section punches 310, 270 which bend the edges of the slits and diamond section punches 300, 280 which open further the apertures formed by the slits to form corrugated projections 12, Fig. 2, joined by saddles 13.

Abstract: 250,478. Wichnevsky, G. Sokolow-. Oct. 12, 1925. Resistances, measuring -An electric gas-testing ap paratus for determining carbon monoxide or dioxide in flue gases by measuring the variations in the resist ance of a conductor located in the gases under test comprises a tubular cooler X, through which the gases are passed, a waterjet pump B placed below the cooler and a filter F and cell A containing gas and air chambers placed at the upper part of the cooler. The gases enter the appar atus at 1, pass through the pipe 2 inside the cooler and through the filter F which consists of a filter cloth 17 and a vessel filled with filtering materials, enclosed in a bell-shaped cover 15 with an oil seal 16. The flue gases are drawn through the filter and along a pipe 6 by the pump B, which is worked by the water supplied to the cooler through the pipe 3. Part of the gases pass through a chamber 18 in which are located wires 23 arranged in opposite arms of a wheatstone bridge, as shown in Fig. 2. Similar wires 24, forming the remaining arms of the bridge, are located in an air chamber 19. In order to compensate for the steam content of the flue gases, which will depend on the temperature of the cooling water, conductors 31, 32 of different temperature coefficients are placed in the cooling water and connected up in adjacent arms of the bridge. When carbon dioxide is to be determined, the wires 23, 24 are heated to about 100‹ C., and the variations in the resistance of the wires 23, due to the lower specific heat-conductivity of carbon dioxide, are measured. If the monoxide is to be determined, the wires are made of platinum and heated to about 400‹ C., the temperature of the wires 23 being increased by the combustion of the carbon monoxide. The measuring instrument 30, which may be a dynamometer when an alternating current source is connected to the bridge, may be graduated to. read in percentages of the dioxide or monoxide.

[Class 79 (v)] [See also Group XXXII] In a railway vehicle of the kind in which the body is supported at one or both ends upon a bogie equipped with a pair of radiating axles, the frames 5, 6 carrying the axles 9, 10, which are swivelly mounted in the bogie by pivots 3, 4, are articulated to each other near the middle of the bogie preferably by a joint 7 permitting relative longitudinal movement, while one of the frames or an extension thereof is connected by a pivot or guide point 8 on the vehicle body, so that, owing to the movement of the body relative to the bogie on a curve, the frames 5, 6 are swung so as to position the axles radially to the curve. In the arrangement shown in Fig. 1, the pivots 3, 4 are arranged directly above the centres of the axles 9, 10, and the guide pivot 8, located on the centre line of the body, is directly associated with the frame 5. Modifications are described in which the pivot 8 is associated with an extension of the frame 6 and in which the pivots 3, 4 are disposed either to the inside or outside of the axles 9, 10. Also, the centre bearing 2 may be disposed centrally or otherwise so as to load the axles equally or unequally. In a modification, Fig. 4, in order that the ordinary lateral movements of the body occurring in normal running may not cause unwanted radiation of the axles, the body pivot 8 is connected to the articulation 7 by means of a link 12 pivotally connected to a swinging bell-crank lever 11<a>, 11<b>. Lateral movements of the body relative to the bogie affect the link 12 only, while movement of the bell-crank lever occurs only when the body pivots on the bogie in negotiating a curve. The necessary relative longitudinal movement between the frames 5, 6 may be provided for by the use of rubber blocks at the joint 7. For effecting a displacement of the connecting-point 7 the use of intermediate hydraulic means may be resorted to.
